“…The highest percentage removal of FFA was 35.54% compared to MS-POBA without template that only has removal percentage of 26.68%. This result was lower compared to previous research using material adsorbent such as Mg, Ca, Sr, and Ba-based silicate and demonstrated in significant reduction of FFA (> 70%) [37]. This can be due to the high surface area with large adsorption sites of different materials.…”

The synthesis of mesoporous material by utilizing palm oil boiler ash (POBA) waste as the silica source and methyl ester sulfonate (MES) surfactant as the template for a high-porosity was investigated for free fatty acids (FFA) adsorption. The research was initiated with silica extraction from POBA by sodium hydroxide addition through the sol-gel precipitation method. Silica modification was carried out with MES surfactant and 3-aminopropyltrimethoxysilane (APTMS) as the co-structure-directing agent (CSDA) in different calcination temperatures. Mesoporous silica-POBA (MS-POBA) free template had a surface area, pore diameter, and pore volume (41.033 m2/g, 4.180 nm, and 0.250 cm3/g) lower than MS-POBA with the template (71.0147 m2/g, 7.923 nm, and 0.524 cm3/g). The ability of MS-POBA to adsorb FFA reached its optimum conditions with an adsorption time of 20 min and an adsorbent dosage of 0.24 g. The FFA removal by MS-POBA with the template was found to have higher adsorption ability, which was 35.54%, compared to the MS-POBA free template of 26.68%. The high porosity of MS-POBA with a template makes the FFA adsorption capacity of this material higher than MS-POBA free template.

“…However, only very limited works reported the MS-POBA material for the removal of FFA in CPO. Recently, Sitinjak [37] used Mg, Ca, Sr, and Ba-based silicate as adsorbent material and further evaluated to find out about the optimum condition of adsorbent MS-POBA. The characteristics of CPO are shown in Table 3.…”
